Tuesday, 19th September
22:43 BST - Pep Guardiola told TNT Sports he felt his side would come through in the end, despite not scoring with a whopping 22 shots in the first half:
"The last two games I didn't know how many chances we missed.
"We played really really good but we were not able to score goals. We were consistent and in the end we won the game.
"Having 22 shots on goal means you are playing really good. It has to be the responsibility of the people in front to have to score the goals. If we scored two goals early in the beginning it would've been completely different.
"We played like West Ham another fantastic game. We missed chances but we were able to create these many sorts of chances and we will win the games."
22:40 BST - Celtic boss Brendan Rodgers was naturally disappointed with tonight's result:
Speaking to TNT Sports he said: "I feel for the players. I think for the first 60 minutes it was a very even game against a team that's doing well and scoring a lot of goals, and we matched them.
"Disappointed with the goal. We made a decision in the game to adjust the wall and it cost us, but we'll take that, I don't mind players making decisions in-game.
